IMPROVEMENT IN MACHINES FOR MAKING AND TWISTING STRANDS IN THE PROCESS 0F MAKING ROPE.

Specification forming part of Letters Patent No. 596, dated February '7, 1838.

To all whom, it may concern,.- Be it known that I, MOSES DAY, 0f Rox bury, in the county of Norfolk and Gommon-` wealth of Massachusetts, have invented, constructed, and applied to use a new and' useul Machine for Forming Strands and IVinding or Packing the Same on a Bobbin, which by means of said machine may be done at one operation, ot' which the following is a specification.

Said machine isL made by an addition here- The end of the flier F F revolves on a horizontal circular tube (represented at g) and at the other end on an axle, which rests on the end of the wooden frame and is covered by a box at b. Through the horizontal circular tube on which the end of the flier revolves tubes of a larger or smaller diameter may be iitted, and through the axis at the other end of the iiier is also a circular tube. A band from the steam-engine or other power passes over a drum at C, and then by another band A passipg over a drum at the opposite end of the shaft at no, and also over a drum at y on the axis of the iiier, a revolving or rotary motion is communicated to the iiier. Through the circular tube in the axis of the tlier,which is sutcientlylarge forthepurpose,passesamandrel, (represented at m,) on the end of which is placed a bobbin B B', which is prevented from turning on the mandrel by applying a sufficient degree of friction between the head of the bobbin and the mandrel. A horizontal motion forward and backward through the circular tube in the axis is communicated to the mandrel by means of an iron rod at fr fr, which at its upper end is fixed to the mandrel and plays freely on a pin passing through it at the lower end at fr. A weight at w, passing overa pulley at q and connected with the iron rod at r, pulls the rod forward,

which is again carried backward by the revolution of a wheel at H, having a heart movement bearing on the rod. This wheel is connected by gearing with the shaft from which the band is carried to the iiier. A small capstan is placed between the opposite sides of the iiier, the ends of which are inserted in the two sides of the flier, as represented at c e. Motion is given to this capstan by means of a beveled wheel of which it is the axis, (represented'at E.) This wheel is connected with another beveled wheel at n, which is fixed on the end of the circular tube on which the flier revolves. As the flier revolves, a rotary motion is given to the capstan at right angles to the revolution of the iiier.

The addition to my spinning-machine by which it becomes a strandmaker consists simply in atxing on the end of the machine a short distance from the circular tube on the end of which the iiier revolves a gage-plate or register-plate R, with holes drilled through it in concentric circles.

The process by which the strand is formed* and wound or packed on the bobbin is as follows: From a bobbin-frame (representedl by Fig. 2 in the annexed drawings) the threads are carried to Fig l and passed through the holes of the gage plate in the same manner as in the common Inode of forming, strands. They are then brought together and passed through the circular tube, whence the strand comes out at o. It then passes round the capstan a suflicient number of times to make it secure. From the capstan it is carried over two pulleys at p p on the side of the iiier, and thence is taken up by the bobbin B B. The rotary motion of the capstan draws forward the strand, which, while it passes from the circular tube at o to the capstan, is twisted or formed by the revolution of the liier. After it has passed from the capstan it is carried over the pulleys at p p to the bobbin B B', upon which it is at the same time wound or packed by the revolution of the liier.

This mode of forming a strand has two prominent advantages over the mode in common use.

First. The twist is given only to that part of the strand which is at any one time passing between the circular tube at 0 and the cn-pstan, so that thc same degree Ot' twist is given to the strand uniformlythroughout its whole length. In the mode in common use the frage-plate and circular tube are permav ceives the greatest degree of twist and the y other parts less, as they are more remote from the spindle.

Secondly. The strand being wound or packed on a bobbin as fast as it is formed,

`there is no need of a great length of walk, as Ain the common mode, but the Whole process of'forming the strand and Winding or packing the same may be performed in a room .only of sufficient size to accommodate the machine and bobbin-trame.I

A machine upon the above construction with the improvement above specified may be used Afor the purpose of forming any num- .ber of threads into a strand or for the purpose oftwisting' spun yarn by increasing or diminishing the number ofand size of the holes in the gage-plate, and the size of the circular tube on which the end of the flier revolves.

The present application is for a patent for the same invention intended-to be described in a former application made by me under` date of 2Mb of January last, with amendments in the description of the same and 'in the manner of stating my claim, as suggested in a letter from the Patent Office under date of November 24, 1837, subscribed by I. W. Hand, Esq., returning my said original application to be thus amended. Y

What I claim as my invention, and desire to secure by Letters Patent, is- A The combination of the gage-plate with a flier, constructed and operated substantially as herein. described.

In testimony whereof I, the said MOSES DAY,

hereunto subscribe my name, in presence of the Witnesses whose names are hereto subscribed, this th day of January, in the year of our Lord 1838, at Boston, in the State of Massachusetts.

MOSES DAY. \Vitnesses:
